Brenna Spector

On a summer afternoon in 1998, six-year-old Iris Neff walked away from a barbecue in her small suburban town...and vanished. Missing persons investigator Brenna Spector has a rare neurological disorder that enables her to recall every detail of every day of her life. A blessing and a curse, it began in childhood, when her older sister stepped into a strange car never to be seen again, and it’s proven invaluable in her work. But it hasn’t helped her solve the mystery that haunts her above all others - and it didn’t lead her to little Iris.

Brenna Spector is held prisoner by the past. She has perfect memory, which allows her to recall in vivid and remarkable detail every moment of every day of her adult life. If only she could remember more from her child-hood…for she's still trying to unravel the mystery of her sister Clea's disappearance, 28 years ago, when Clea was 17. But now her obsession with finding out what happened to Clea is taking a toll on her own teenage daughter, Maya, who's been very secretive lately. And when Maya goes missing, Brenna fears her worst nightmare has come true.
